This section describes some recommended performance tuning configurations to optimize BAM. It assumes that you have set up the BAM server on Unix/Linux, which is recommended for a production deployment. If you have high volume of data with high concurrency, we also recommend you to use a distributed BAM setup. For instructions, see our product deployment and clustering guide.
